No spark Johnson 48.

Lost spark on my Johnson 48 SPL. When I was checking it, I got it back for very short periods of time, but then it disappeared completely. I checked every wire, every connection, disconnected Black/Yellow wire at the Power pack, disconnected yellow wires from the rectifier, didn't help (basically followed some of these steps http://forums.iboats.com/forum/engi...-outboards/399842-94-evinrude-48-spl-no-spark). I would think that if Power Pack is bad, it wouldn't work intermittently . So, I got under the flywheel, and noticed that pads inside flywheel have significant groove. Also ignition trigger/sensor (this thing with thin metal plate in the middle http://www.ebay.com/itm/OMC-Johnson...Oem-/251884600780?hash=item3aa57dfdcc&vxp=mtr) is grinded down to the plastic. I pushed it forward as far as I can, and was able to start the motor for a few seconds, but this trick didn't work second time. I was wondering if there is a specific gap required between the flywheel pad and the trigger?, and what would be better to change trigger or flywheel?
 
Have you inspected the starter motor ??----------Slow cranking means you will have poor spark.--------------And the parts under the flywheel are actually very reliable and rarely need replacement.----------You certainly do not adjust this stuff if you are unaware of how they look or should look.
 
I think I found the problem. There is no continuity in Charge Coil and Lamination Assembly (brown to brown/yellow wires). Hence no resistance no DVA, I thinks this table list this coil under stator http://www.outboardignition.com/page40.asp in 5-60 1992-2000 row.

I didn't test it, but the cranking seems to be good. I have this boat for a while, and can sort off "hear" when cranking rev drops. At least I think I can :)
 
I think I found the problem. There is no continuity in Charge Coil and Lamination Assembly (brown to brown/yellow wires). I assume there should be one right? I found a table that list my engine size and year but actually lists stator with brown to brown/yellow wires resistance and DVA. My stator actually has yellow, yellow /blue, and yellow/purple wires.

What I'm not sure off, is when flywheel pads are passing over ignition sensor (trigger), does it have to have a full contact (metal on metal), or some gap is acceptable. I looked at some other triggers online, and the metal strip seems to be flush with the plastic casing. This made me thing that the problem is not in the gap between flywheel pad and trigger, but somewhere else.
